Chrysanthemum plant named ‘Yogwendolyn’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Yogwendolyn’, characterized by its upright and somewhat outwardly spreading plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; daisy-type inflorescences with elongated oblong-shaped ray florets; white-colored ray florets; and natural season flowering in early September in the Northern Hemisphere.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yogwendolyn’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum×morifolium,commercially known as a garden-type Chrysanthemum and hereinafterreferred to by the name ‘Yogwendolyn’.

The new cultivar is a product of a planned breeding program conducted bythe Inventor in Gainesville and Alva, Fla. The objective of the breedingprogram is to create new garden-type Chrysanthemum cultivars havinginflorescences with desirable inflorescence forms, attractive floretcolors and good garden performance.

The new Chrysanthemum originated from a cross-pollination made in March,2001 in Gainesville, Fla., of the Chrysanthemum×morifolium cultivarAtlantico, disclosed in U.S. Plant Pat. No. 11,606, as the female, orseed, parent with the Chrysanthemum×morifolium cultivar Tracy, disclosedin U.S. Plant Pat. No. 8,609, as the male, or pollen, parent. The newChrysanthemum was discovered and selected by the Inventor as a singleflowering plant within the progeny of the stated cross-pollination grownin a controlled environment in Alva, Fla. in September, 2001. Theselection of this plant was based on its desirable inflorescence form,attractive floret coloration and good garden performance.

Asexual reproduction of the new cultivar by terminal vegetative cuttingsin a controlled environment in Alva, Fla. since January, 2002, has shownthat the unique features of this new Chrysanthemum are stable andreproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yogwendolyn has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Yogwendolyn’. These characteristics incombination distinguish ‘Yogwendolyn’ as a new and distinct cultivar:

-   -   1. Upright and somewhat outwardly spreading plant habit.    -   2. Freely branching habit; dense and full plants.    -   3. Uniform and freely flowering habit.    -   4. Daisy-type inflorescences with elongated oblong-shaped ray        florets.    -   5. White-colored ray florets.    -   6. Natural season flowering in early September in the Northern        Hemisphere.

In side-by-side comparisons conducted in Alva, Fla., plants of the newChrysanthemum differed from plants of the female parent, the cultivarAtlantico, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were larger than plants of        the cultivar Atlantico.    -   2. Plants of the new Chrysanthemum flowered about two weeks        earlier than plants of the cultivar Atlantico when grown under        natural season conditions.    -   3. Plants of the new Chrysanthemum had smaller inflorescences        than plants of the cultivar Atlantico.    -   4. Plants of the new Chrysanthemum and the cultivar Atlantico        differed in ray floret coloration as plants of the cultivar        Atlantico had yellow bronze-colored ray florets.    -   5. Plants of the new Chrysanthemum had longer lasting        inflorescences than plants of the cultivar Atlantico.

In side-by-side comparisons conducted in Alva, Fla., plants of the newChrysanthemum differed from plants of the male parent, the cultivarTracy, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were not as mounded as plants        of the cultivar Tracy.    -   2. Plants of the new Chrysanthemum flowered about ten days        earlier than plants of the cultivar Tracy.    -   3. Plants of the new Chrysanthemum flowered more uniformly than        plants of the cultivar Tracy.    -   4. Plants of the new Chrysanthemum had smaller inflorescences        than plants of the cultivar Tracy.

Plants of the new Chrysanthemum can be compared to plants of theChrysanthemum cultivar Stephanie, disclosed in U.S. Plant Pat. No.9,445. In side-by-side comparisons conducted in Alva, Fla., plants ofthe new Chrysanthemum differed from plants of the cultivar Stephanie inthe following characteristics:

-   -   1. Plants of the new Chrysanthemum were stronger, slightly        larger and more rounded than plants of the cultivar Stephanie.    -   2. Plants of the new Chrysanthemum had lighter green-colored        foliage than plants of the cultivar Stephanie when grown under        natural season conditions.    -   3. Plants of the new Chrysanthemum flowered two to three days        earlier than plants of the cultivar Stephanie when grown under        natural season conditions.    -   4. Plants of the new Chrysanthemum had smaller inflorescences        than plants of the cultivar Stephanie.

Plants of the new Chrysanthemum can also be compared to plants of theChrysanthemum cultivar Starlet White, not patented. In side-by-sidecomparisons conducted in Alva, Fla., plants of the new Chrysanthemumdiffered from plants of the cultivar Starlet White in the followingcharacteristics:

-   -   1. Plants of the new Chrysanthemum were larger than plants of        the cultivar Starlet White.    -   2. Plants of the new Chrysanthemum had larger inflorescences        than plants of the cultivar Starlet White.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart, 1995 Edition, except where generalterms of ordinary dictionary significance are used. The followingobservations and measurements describe plants grown in Leamington,Ontario, Canada during the late summer and early fall in an outdoornursery under conditions and practices which approximate those generallyused in commercial garden-type Chrysanthemum production. One cutting wasplanted in a 15.25-cm container in mid-July, 2004. Plants were grownunder natural season conditions. During the production of the plants,temperatures ranged from 10° to 32° C. Measurements and numerical valuesrepresent averages for typical flowering plants.
